Abstract
ABSTRACT OF THE DISCLOSURE
The apparatus comprises a bearing structure (2), a slidably movable print head (6) guided in said bearing structure, a dragging unit (22, 23) adapted to move a sheet (7) to be printed under the print head and exhibiting dragging members (22) directly acting on the sheet, a plate-like body (4) provided with a write surface (5) located under the print head and representing a rest surface for the sheet, the bearing surface and plate-like body are substantially in mutual contact and a raised position for putting the sheet in place, in which the dragging members directly acting on the sheet are located in the plate-like body substantially below the write surface.

Claims (12)
1. A portable printing apparatus comprising:
- a bearing structure:
- a print head slidably movable and guided within said bearing structure;
- a dragging unit adapted to move a sheet to be printed under said print head and exhibiting dragging members directly acting on said sheet, wherein said portable printing apparatus further comprises:
- a plate-like body in which a write surface located underneath said print head and adapted to rest on said sheet to be printed is provided:
- hinge means for oscillatably connecting the bearing structure to the plate-like body according to a substantially horizontal axis, from an operating position in which they are in mutual contact to a raised position for the positioning of said sheet, said dragging members directly acting on said sheet being disposed in said plate-like body substantially below said write surface.
- a bearing structure:
- a print head slidably movable and guided within said bearing structure;
- a dragging unit adapted to move a sheet to be printed under said print head and exhibiting dragging members directly acting on said sheet, wherein said portable printing apparatus further comprises:
- a plate-like body in which a write surface located underneath said print head and adapted to rest on said sheet to be printed is provided:
- hinge means for oscillatably connecting the bearing structure to the plate-like body according to a substantially horizontal axis, from an operating position in which they are in mutual contact to a raised position for the positioning of said sheet, said dragging members directly acting on said sheet being disposed in said plate-like body substantially below said write surface.
2. The apparatus as claimed in claim 1, wherein said bearing structure comprises:
- a stiff rod slidably carrying said print head, - two flattened side elements between which the stiff rod is rigidly engaged at the respective ends thereof, and - at least an upper guide crosspiece to guide said print head and engaged to said side elements.
- a stiff rod slidably carrying said print head, - two flattened side elements between which the stiff rod is rigidly engaged at the respective ends thereof, and - at least an upper guide crosspiece to guide said print head and engaged to said side elements.
3. The apparatus as claimed in claim 1, wherein closure means adapted to rigidly clamp the bearing structure to said plate-like body in the operating position is provided.
4. The apparatus as claimed in claim 3, wherein said closure means comprises at least a lever operable by hand, at least a hooked element connected to said lever, and a restraining element adapted to come into engagement with said hooked element.
5. The apparatus as claimed in claim 4, wherein said bearing structure comprises a stiff rod slidably carrying said print head and two substantially flat side elements between which the stiff rod is rigidly engaged, and wherein two of said hooked elements are provided, each of them close to one of said side elements, as well as a stem for the mutual engagement between said hooked elements passing through the inside of said stiff rod.
6. The apparatus as claimed in claim 2, wherein said stiff rod exhibits, at each end thereof, at least an extension extending away from its axis and adapted to be engaged to the adjacent side element thereof.
7. The apparatus as claimed in claim 1, wherein said dragging unit comprises a drive unit located in said bearing structure and a gearing to transmit the motion from said drive unit to said dragging members, said gearing being disposed partly in said bearing structure and partly in said plate-like body and being adapted to become automatically engaged when the bearing structure is lowered to its operating position.
8. The apparatus as claimed in claim 1, wherein said dragging members are comprised of a pair of rotating elements located spaced apart from each other in a position close to said side elements and adapted to engage with corresponding edge perforations of the sheet, and wherein an upper plate is provided which is engaged at the lower part thereof to said bearing structure and substantially matches the shape of the write surface, said sheet being included between said upper plate and write surface in said operating position.
9. The apparatus as claimed in claim 8, wherein said rotating toothed elements are selectively movable away from or close to each other depending upon the width of the sheet to be printed, and wherein said upper plate exhibits, close to at least one of its side edges, at least a pair of slits substantially disposed in side-by-side relation and adapted to be selectively passed through at least partly by the corresponding rotating toothed element.
10. The apparatus as claimed in claim 1, wherein said dragging members comprise a number of friction rollers and wherein provision is made for:
- an upper plate engaged at the lower part thereof to said bearing structure, substantially matching the shape of the write surface and having a number of apertures in register with said friction rollers, and - a number of pressing counter-rollers engaged to said plate disposed in register with said apertures and acting against the spring action of said friction rollers, said sheet being inserted between said upper plate, pressing counter-rollers and write surface in said operating position.
- an upper plate engaged at the lower part thereof to said bearing structure, substantially matching the shape of the write surface and having a number of apertures in register with said friction rollers, and - a number of pressing counter-rollers engaged to said plate disposed in register with said apertures and acting against the spring action of said friction rollers, said sheet being inserted between said upper plate, pressing counter-rollers and write surface in said operating position.
11. The apparatus as claimed in claim 1, wherein a strip made of elastomeric material is provided in engagement with said write surface at the write line of the print head.
12. The apparatus as claimed in claim 11, wherein said elastomeric material is substantially adiprene.
